In [URL="http://en.wikipedia.org/wiki/Computer_hardware"]computer hardware[/URL], [B][URL="http://en.wikipedia.org/wiki/Globally_Unique_Identifier"]GUID[/URL] Partition Table[/B] ([B]GPT[/B]) is a standard for the layout of the [URL="http://en.wikipedia.org/wiki/Partition_table"]partition table[/URL] on a physical [URL="http://en.wikipedia.org/wiki/Hard_disk"]hard disk[/URL]. Although it forms a part of the [URL="http://en.wikipedia.org/wiki/Extensible_Firmware_Interface"]Extensible Firmware Interface[/URL] (EFI) standard ([URL="http://en.wikipedia.org/wiki/Intel"]Intel's[/URL] proposed replacement for the [URL="http://en.wikipedia.org/wiki/IBM_PC"]PC[/URL] [URL="http://en.wikipedia.org/wiki/BIOS"]BIOS[/URL]), it is also used on some [URL="http://en.wikipedia.org/wiki/BIOS"]BIOS[/URL] systems because of the limitations of [URL="http://en.wikipedia.org/wiki/Master_Boot_Record"]MBR[/URL] partition tables, which restrict a disk partition's size to a maximum of 2.2 [URL="http://en.wikipedia.org/wiki/Terabyte"]TB[/URL] (2.2 × 1012 [URL="http://en.wikipedia.org/wiki/Byte"]bytes[/URL]).[URL="http://en.wikipedia.org/wiki/GPT_Disk#cite_note-UEFIDrivePartitionFAQ-0"][1][/URL] GPT allows for a maximum disk and partition size of 9.4 [URL="http://en.wikipedia.org/wiki/Zettabyte"]ZB[/URL] (9.4 × 1021 bytes).[URL="http://en.wikipedia.org/wiki/GPT_Disk#cite_note-UEFIDrivePartitionFAQ-0"][1][/URL][URL="http://en.wikipedia.org/wiki/GPT_Disk#cite_note-Redmondmag64bitQuestion-1"][2][/URL]
